The first diastereoselective cycloaddition of a nitrile oxide with a homoallylic alcohol is discussed. The reaction of benzonitrile oxide with the magnesium alkoxides of chiral homoallylic alcohols has been shown to proceed with good diastereoselectivity, favoring the syn isomer of the resulting 2-isoxazoline.
讨论了一氧化氮与均丙醇的第一次非对映选择性环加成反应。与手性高烯丙基醇的醇镁苄腈氧化物的反应已被证明具有良好的非对映选择性进行,有利于顺式的得到的2-异恶唑啉的异构体。
